Speaking of tourist trap, how about let's just forgo all pretenses, and admit that this is all for commercialism

and souvenir shopping is the main reason why you are all here?

The exhibit of the Emperor Sedan is now directly inside this souvenir shop. Pay and you get to have a picture taken with it, up close and personal. Pay more you get to move to the left side, where you can dress up and the Emperor and the Empress and have your picture taken on a replica throne.
